iirc they live n die as a collective so i spose if any wash up it is often many in one go.

if it has been calm for a while any dead ones will get stirred up at the same time.

ages ago i saw a bunch of freshish ( not very fresh ) ones that still had some spines and contents after a storm and tide had swirled em out of the sand onto the beach.

as soon as you go below lowest low tide there are a huge variety of odd beasties, sea squirts have ace comedy value if one's chums have never been handed one before, especially when the single cavity two holes thing is explained,
there is a high probability that our gt gt ( to the power N where N is a very big number ) grannie was a sea squirt of some sort.
iirc tunicates are first in the fossil record for anything resembling a gut with two ends
